El Monte Airport (just south of Pasadena) -- I remember when parking over night was not so strict. In collage, my buddies and I used to drive my 1972 VW van all over California and neighboring states. We parked over night at grocery stores, department stores, city streets and even on Highway 1 along the Central Coast. Although we anticipated the 6am knock on window from police, we usually got away with a stern warning.
The Cessna doesn't have much to do with this story but the sign reminds me of the freedoms we used to enjoy on the open road way back when.
